Of course the nefarious supervillain making this virus spent all that time putting those insertions in (from HIV or fish presumably) and all it does is delete them.

In context

A single line often inverts meaning once you see what it answers, so neighbouring messages are always shown.

The insertions not needed so put SC2 under the right situation and it starts to delete. Just like im cell culture the FCS and the QTQTN can be deleted.

@Andrew Rambaut yes indeed - may get a somewhat different alignment with the nucleotides but the point remains that these are hotspots for deletions. Mechanism TBD but could be swapping out a shorter sequence with end homologiesy via copy-choice.

Wow Bob, that's amazing.

Important for the origins argument as well - if these indels between SC1 and SC2 are natural and in play for variation, then the PRRA insert is natural as well.
